Wow, what to say, it seems that you are right (apart from the fact that they are 4 and not 2 but that says little)
in essence, however, nothing changes, you can also call Avalanche (including the Producer) but since the only difference between these two models is the groove (e forse, dico forse, qualche quasi impercettibile differenza al bordo più esterno dello shape), in fact Avalanche or Sasquatch, the yoyo is always the same, the rest is just poetry and hype .
anyway congratulations, collectively you have a interesting piece.
p.s. if, to complete the information and by virtue of the ease of misunderstandings that these two almost identical models can generate, you had linked the page of the bolg in your first post we would have avoided half the page of unnecessary messages ;D
